[Effect] As described above, according to the present invention, the polishing material reclaiming device is integrally connected to the upper portion of the pachinko ball polishing unit, and the polishing material is regenerated by the stirring member common to the screw feeder for pachinko ball polishing. No special drive source is required, and the device becomes significantly compact.

With the pachinko ball polishing, a part of the polishing material is always automatically polished, so that the polishing material can be regenerated during the opening hours of the hole. Conventionally, when reclaiming the abrasive, the abrasive is once collected and regenerated, so the operation of the pachinko ball polishing apparatus must be stopped during regeneration.
For this reason, the reproduction work had to be performed outside the business hours of the hall, but the present invention reasonably eliminates this time loss.

When the polishing chamber for polishing the abrasive is formed into a polygonal cylindrical body, an escape place for the abrasive during the regrinding occurs at the corner, and a cushioning effect is exerted on the abrasive when the agitating member agitates. Therefore, since an excessive pressure is not applied to the polishing material, an appropriate polishing pressure can be obtained, and abrasion and cracking of the polishing material are reduced, so that the replenishing amount of the polishing material can be small.

Since the polishing debris is removed, the polishing room for polishing the polishing material can be kept clean, and the pachinko balls that have been polished can be supplied.
